Help! Zund engineer or similar urgent required
Hello,
I am looking for a Zund engineer or any mechanical engineer to fix a router tool for us. It is quite urgent.
Basically the collet of our Zund router tool snapped inside, see photo. I have contacted Zund UK but they said they can’t do it, no tools blah blah blah and offered us a new one to buy.
We have tried to remove that but not much success, we don’t know how to open the tool.
I was wondering if there is a mechanical engineer around here or someone who has experience with this sort of issue.
Many thanks,
George

looking at that they undo with a special socket that locks into the pinholes on the face of them rings, probs would be making a tool to work on them securing nuts, has the shaft actually broken off hard to tell from the photo’s. If it has then locating a new part would be hard, this spins at very high RPM so would require balancing on special equipment.Post some photos of the end of the shaft please

Just looked at pics again presuming you have a snapped collet in the head, are the normally just push fit screw in etc, may have an idea how to remove once i know.
Collets on std router are different

Hi Kev,
Sorry for late answer, I did a trip to Luton.
See image attached. The collet has thread inside to connect with the shaft. The shaft is not broken.Cheers

Can you not drill a small hole and use either a left handed thread bolt or a tool call an easy out I think you can purchase the tool from screwfix for about £10
Hope it helps

Ok i’m presuming that the bit left in is tubular if it is i would modify an easy out either making it very stubby and you may have to weld an extension for it to reach. You can make your own with a bit of flat bar cutting at a taper then grinding edges to sharp angle. Has you tap it into place it will dig in then use a pair of grips to hopefully unwind. I can come have a look if you aren’t confident to do yourself

Morning,
I have tried already such a tool but the collet feels very hard steel and the easy out tool does not get any grip on it.
I have to go to ScrewFix to buy that tool. The one I have is from Maplin and does not get any grip.I also tend to believe something went wrong inside, maybe the collet has been badly screwed into the shaft, because I got grip on it with a flat end scredriver but is feels proper stuck.
I try to call the manufacturer (a German company) to see if they can advise hot to open the router tool perhaps I will have more luck.
Cheers
